Restoring Stained Plaster

What is a muriatic acid wash?

Using a blend of muriatic acid, water and commercial detergents, we’re able to remove unsightly blemishes from your plaster surface swimming pool typically caused by algae, minerals, chlorine and dirt.

When should I acid wash my swimming pool?

We recommend acid washing your swimming pool when regular swimming pool chemicals no longer have an affect on stains and discoloration in your plaster. Muriatic acid washing removes a thin layer of your swimming pool’s plaster surface, revealing a new finish beneath. As a result, it is important to understand that mild etching is possible, causing a slightly rougher finish.

The Environmental Protection Agency regulates muriatic acid as a toxic substance. Muriatic acid is a hazardous liquid which must be used with care. The acid itself is corrosive, and concentrated forms release acidic mists that are also dangerous. If the acid or mist come into contact with the skin, eyes, or internal organs, the damage can be irreversible or even fatal in severe cases. The use of personal protective equipment is essential.

Skin Contact – If muriatic acid comes into contact with your skin, flush immediately with plenty of water for at least 15 minutes and remove any contaminated clothing. In case of serious skin contact, use water, a disinfectant soap and anti-bacterial cream. Seek immediate medical attention.

Eye Contact – If muriatic acid or acidic mists get into your eyes, immediately flush with plenty of water for at least 15 minutes. Seek immediate medical attention.

Ingestion – If swallowed, do not induce vomiting. Seek immediate medical attention.

Inhalation – If you inhale muriatic acid vapors or mists, seek fresh air and immediate medical attention.
